摘　　要：从既有设备概况、路网构成、存在的主要问题3个方面介绍拉萨铁路枢纽概况,根据拉萨西站解编作业量及列车对数预测结果,研究解编系统规划改造方案。结合拉萨市铁路发展规划和枢纽总布置图,考虑未来运输发展需求,综合比较拉萨西站采用一次建成一级二场(方案Ⅰ)与近期采用一级二场、远期采用一级三场(方案Ⅱ)2个方案,推荐拉萨铁路枢纽解编系统规划改造方案宜采用后者。This paper expounds general status of Lhasa railway hub from 3 aspects of exiting equipment status, railway network composition and main exiting problems. According to uncoupling operation volume and forecast result of train numbers in Lhasa West Station, the planning and reconstruction program of its uncoupling system was studied in the paper. Combining with Lhasa railway development plan and the general distribution diagram of Lhasa railway hub, and considering the transport development demand in future, the paper compares 2 programs, which are program I--constructing 1 level 2 yards for completion at once and program II--applying 1 level 2 yards in short-term and 1 level 3 yards in long-term, finally, the program II was recommended to apply in planning and reconstruction program of the hub uncoupling system.
